Privacy Policy
Last Updated & Reviewed: September 25, 2026 • Effective Date: September 1, 2026
1. Privacy by Architecture (Zero-Backend Calculations)
At AnyCalcHub (available at https://anycalchub.online), your personal privacy is protected at the architectural level. Unlike traditional web applications that transmit your inputs to centralized databases, AnyCalcHub executes 100% of mathematical calculations directly within your device's local web browser.
When you enter sensitive data—such as your annual income, loan principal amounts, mortgage tenures, dates of birth, or body weight—that information is never transmitted across the internet to our servers. Your figures remain on your phone, tablet, or computer at all times.
2. Browser Local Storage & Session Data
AnyCalcHub utilizes standard web storage APIs (localStorage and sessionStorage) to power client-side productivity features, including:
- Workspace & Saved Calculations: Saving calculation cards, custom labels, and bookmarks.
- Recent Calculations History: Retaining recent math results locally for quick retrieval.
- UI Preferences: Dark/light mode theme toggles and preferred currency selection (USD, INR, EUR, GBP).
This information resides solely inside your local browser sandbox. You can permanently erase all stored data at any time by clearing your browser cookies and site storage, or by clicking "Clear History" inside the Workspace tab.
3. Google AdSense & Third-Party Advertising Disclosures
AnyCalcHub may display advertisements served by Google AdSense and authorized third-party ad networks to fund free, open access to all 136 calculation tools. In accordance with Google's publisher policies, please review the following disclosures:
- Third-Party Vendors & Cookies: Third-party vendors, including Google, use cookies to serve ads based on a user's prior visits to this website or other websites across the Internet.
- Google Advertising Cookies: Google's use of advertising cookies enables it and its partners to serve relevant ads to our users based on their navigation history across AnyCalcHub and other sites on the web.
- Web Beacons & Tags: Third-party ad networks may also use web beacons, JavaScript, or action tags to measure the effectiveness of their advertisements and personalize advertising content.
How You Can Opt Out of Personalized Advertising:
Users may opt out of personalized advertising by visiting Google Ads Settings. Alternatively, you can opt out of third-party vendor cookies for personalized advertising by visiting www.aboutads.info or the European Interactive Digital Advertising Alliance at youronlinechoices.eu.
4. Web Server Log Files & Analytics
Like virtually all website operators, our hosting infrastructure (Cloudflare Pages) automatically logs standard technical metadata when you request web pages. This includes:
- Internet Protocol (IP) address
- Browser user-agent string and version
- Referring and exit URLs
- Date and timestamp of request
- HTTP status response codes
Log file information is strictly utilized to defend against distributed denial-of-service (DDoS) attacks, analyze aggregated traffic trends, and verify reliable site uptime. Log files are not linked to personally identifiable information.
5. GDPR Compliance & Data Subject Rights (European Union / EEA)
If you are a resident of the European Economic Area (EEA), you possess statutory rights under the General Data Protection Regulation (GDPR), including:
- Right of Access: The right to request copies of your personal data.
- Right to Rectification: The right to request correction of inaccurate data.
- Right to Erasure: The right to request deletion of your data ("Right to be forgotten").
- Right to Restrict Processing: The right to limit how we process your personal data.
- Right to Data Portability: The right to receive your data in a structured, machine-readable format.
Because AnyCalcHub does not create user accounts, require email logins, or collect personal identifying data on servers, no centralized personal profile is maintained. For any inquiries, contact our data desk at contact@anycalchub.online.
6. CCPA & CPRA Notice for California Residents
Under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA), California residents have specific rights regarding their personal information:
- Right to Know: You may request disclosure of what personal information is collected.
- Right to Delete: You may request deletion of personal information collected from you.
- Do Not Sell or Share My Personal Information: AnyCalcHub does not sell your personal calculation data to third-party data brokers.
- Non-Discrimination: We will never discriminate against you for exercising your privacy rights.
7. Children’s Online Privacy Protection (COPPA)
Protecting the online privacy of children is of paramount importance. AnyCalcHub does not knowingly collect or solicit personally identifiable information from children under the age of 13. All educational math tools operate without requiring registration or the submission of personal data. If you believe a child has provided personal details, please contact us immediately for prompt removal.
